* [Design] Compatibility switches
This introduces a pattern for versioning breaking behaviour changes in
minor releases of MVC.
The general plan is that application developers choose a release version
(2.0, 2.1, Latest) as their baseline which determines the effective
'defaults' for some options. Anything the developer sets explicitly is
an override and always wins.
Then we add a version setting to the template to point to the current
release.
This allows us to be progressive with fixing issues and improving areas
that don't work well, but offers the developer some choice about when to
adopt new behaviours. In effect, we separate new behaviours from the
libraries that develiver them. Apps can update the version, and then opt
in to new behaviours as a separate change.
* Be more american
* improve docs, add example
* Fix visibility
* Fix broken test
* Add test
* Docs!
* The rest of the tests
* fix example
* Adding docs
* PR feedback
This test uses the new features in the service provider to verify that we
don't reference any scoped services from singletons.
Note that this can't really cover the cases where we have optional
services or where we replace default services (like DI for controllers).
You'll just have to be careful.
* Added ControllerFeature and ControllerFeatureProvider to perform controller discovery.
* Changed controller discovery to use application parts.
* Changed ControllerActionDescriptorProvider to make use of Application parts.
* Simplified AddControllerAsServices to not accept any parameter and perform
controller discovery through the ApplicationPartManager in the IMvcBuilder
and IMvcCoreBuilder. Assemblies should be added to the ApplicationPartManager
in order to discover controllers in them.
This commit introduces application parts as a concept on MVC.
An application part is an abstraction that allows you to expose some
feature or corncern in a way that is decoupled from their underlying source.
Examples of this include types in an assembly, emdeded resources, files on
disk etc.
Application parts are configured during startup by adding or removing them from
the application part manager available as part of IMvcBuilder and IMvcCoreBuilder.
The application part manager provides the ability to populate features from the
list of available application parts by using a list of application feature providers.
Application feature providers are responsible for populating a given feature given a
list of application parts.
Examples of application providers can be a ControllerFeatureProvider
that goes through the list of application parts, sees which one of those parts exposes types,
determines which of those types are controller types, and adds them to a ControllerFeature
that holds a list of all the types that will be considered controllers in the application.
